Answer:

The answers are in the explanation. The pH is 5.91

Explanation:

The CH3NH2 reacts with HCl as follows:

CH3NH2 + HCl → CH3NH3⁺ + Cl⁻

When 200mL of HCl are added, the moles of CH3NH2 and HCl are reacting completely producing CH3NH3+ and Cl-. That means the species present are:

no H+. All reacted

yes H2O. Because the water is present in the solutions of HCl and CH3NH2

yes Cl-. Is a product of the reaction

Yes CH3NH2. Is consumed in the reaction but comes from the equilibrium of CH3NH3+

yes CH3NH3+. Is the other product of the reaction. MAJOR SPECIES

When 300.00mL of HCl are added, 100mL are in excess:

yes H+. Is in excess: H+ + Cl- = HCl in water. MAJOR SPECIES. Determine the pH of the solution.

yes H2O. Is present because the reactants are diluted.  

yes Cl-. Is a product of reaction and comes from HCl.

Yes CH3NH2. The reactant is over but comes from the equilibrium of CH3NH3+

yes no CH3NH3+. Yes. Is a product and remains despite HCl is in excess.

To find the pH:

At equivalence point the ion that determines pH is CH3NH3+. Its concentration is:

0.100L * (0.200mol/L) = 0.0200 moles / 0.300L = 0.0667M CH3NH3+

The equilibrium of CH3NH3+ is:

Ka = Kw/kb = 1x10-14/4.4x10-4 = 2.273x10-11 = [H+] [CH3NH2] / [CH3NH3+]

As both [H+] [CH3NH2] comes from the same equilibrium:

[H+] =  [CH3NH2] = X

2.273x10-11 = [X] [X] / [0.0667M]

1.5159x10-12 = X²

X = 1.23x10-6M = [H+]

As pH = -log [H+]

pH = 5.91

The pH at the equivalent point for this titration is "5.91".

\(CH_3NH_2 = 0.200\ M\\\\ \text{volume} = 100.0\ mL = 0.100\ L\\\\HCl = 0.100\ M\\\\\)

We must now quantify the pH well at the equivalence point.

We know that even at the point of equivalence, moles of acid and moles of the base are equivalent. As such, first, we must calculate the number of moles of the given base.

Calculating the Moles in \(CH_3NH_2 = 0.200\ M \times 0.100\ L = 0.0200\ moles\)

Calculating the Moles in \(HCl = 0.0200 \ moles\)

Calculating the volume of \(HCl\):

\(\to \text{Molarity} = \frac{ \text{moles}}{\text{volume \ (L)}} \\\\\to \text{Volume} = \frac{\text{moles}}{\text{molarity}}\\\\\)

                \(= \frac{0.0200 \ moles}{ 0.100\ M}\\\\= 0.200 \ L\\\\= 200 \ mL\\\\\)

Calculating the reaction among the acid and base:

\(CH_3NH_2 + HCl \longrightarrow CH_3NH_3^{+} + Cl^-\)

\(0.0200 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.0200 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.0200\)

Therefore the conjugate acid of the bases exists at the standard solution.

Then we must calculate the new molar mass of \(CH_3NH_3^+\).

Total volume\(= 100 + 200 = 300\ mL = 0.300\ L\)

\([CH_3NH_3^+] = \frac{0.0200\ mole}{ 0.300\ L}= 0.0667\ M\)

Using the ICE table

\(CH_3NH_3^+ + H_2O \longrightarrow CH_3NH_2 + H_3O^+\)

\(I \ \ \ \ \ \ \ \ \ \ 0.0667 \ \ \ \ \ \ \ \ \ 0\ \ \ \ \ \ \ \ \ 0\\\\C\ \ \ \ \ \ \ \ -x\ \ \ \ \ \ \ \ +x \ \ \ \ \ \ \ \ +x\\\\E \ \ \ \ \ \ \ \ \ \ \ \ 0.0667-x \ \ \ \ \ \ \ \ \ \ \ \ +x \ \ \ \ \ \ \ \ \ \ \ \+x\\\\\to Ka = \frac{[CH_3NH_2] [H_3O^+] }{[CH_3NH_3^+]}\)

Calculating \(K_a\) from \(K_b\)

\(\to K_a \times K_b = 1\times 10^{-14}\\\\\to K_a = \frac{1\times 10^{-14}}{4.4\times 10^{-4}} = 2.27\times 10^{-11}\\\\\)

                           \(= 2.27\times 10^{-11} \\\\= x\times \frac{x}{(0.0667-x)}\)

The x in the 0.0667-x can be ignored since the Ka value is just too small and it also does not follow the five percent criteria.

\(\to 2.27 \times 10^{-11} \times 0.0667 = x_2\\\\\to x_2 = 1.515\times 10^{-12}\\\\\to x = 1.23\times 10^{-6}\ M\\\\\to [H_3O^+] = x = 1.23\times 10^{-6}\ M\\\\\)

We have the formula to calculate pH.

\(\to pH = - \log [H_3O^+] = - \log 1.23\times 10^{-6}\ M= 5.91\)

The pH at the equivalent point for this titration is "5.91".

The transfer function, h(f), of the filter can be derived in terms of r, l, c, and w.

It describes the relationship between the input and output voltages.

The transfer function, h(f), of the given filter can be derived by analyzing the components and their interactions within the circuit. It represents the relationship between the input voltage (Vin) and the output voltage (Vout) as a function of frequency (f).

To derive the transfer function, one would need to consider the impedance of the components at different frequencies. The filter consists of resistors (r), inductors (l), and capacitors (c), each contributing to the overall impedance and affecting the signal transmission. By evaluating the impedance values and using the principles of circuit analysis, it is possible to derive an equation for h(f) in terms of r, l, c, and the angular frequency (w = 2πf).

Understanding the transfer function provides insights into how the filter behaves with different input frequencies. It helps in determining the frequency response of the filter and its ability to attenuate or pass certain frequency ranges.

Both Technicians A and B are correct that driveline binding can result from uneven tire circumferences and that uneven tire circumferences can be corrected by shaving the tires.

Employed in almost every industry, technicians are skilled professionals. Different systems and pieces of equipment are serviced, repaired, installed, and replaced by them. The ability to read instructions and communicate clearly is a requirement for technicians, who frequently collaborate with other skilled workers. If a four-wheel vehicle is driven on dry highways for a significant amount of time, you can expect to experience drivetrain binding. Transmission windup can also happen because the front and rear driveshafts don't rotate at the proper frequency or speed, which is affected by the direction you're driving. On these vehicles, the drivetrain rotates more quickly at the front than the rear. Many part-time 4 wheel drive transfer cases lack a center differential, which causes them to jam.

According to the question: the Stress in cylinder is 1813 N/mm^2.

A cylinder is a three-dimensional geometric shape with two circular bases, one at each end, connected by a curved surface. The curved surface is a straight line connecting the two circular bases and is called the side or lateral surface. The two circular surfaces that make up the cylinder are called the bases.

The initial stress in the bar and cylinder can be calculated using the following equation:
Stress = Load / (Area of bar x Area of cylinder)
Stress in bar = 1000 kN / (π*(75/2)^2 * π*(75/2)^2) = 2300 N/mm^2
Stress in cylinder = 1000 kN / (π*(75/2)^2 * π*(100/2)^2) = 1875 N/mm^2
The final stress in the bar and cylinder can be calculated using the following equation:
Stress = (Load + Change in Length * Modulus of Elasticity * Coefficient of Linear Expansion * Change in Temperature) / (Area of bar* Area of cylinder)
Stress in bar = (1000 kN + (75 mm * 200000 N/mm^2 * 0.0000012/C * -150C)) / (π*(75/2)^2 * π*(75/2)^2) = 2250 N/mm^2
Stress in cylinder = (1000 kN + (75 mm * 80000 N/mm^2 * 0.000005/C * -150C)) / (π*(75/2)^2 * π*(100/2)^2) = 1813 N/mm^2

(a) The probability of drawing a black fuse from the second toolbox is 4/7.

(b) The probability of drawing a white fuse from the second toolbox is 3/7.

(c) The probability that one fuse is white is 27/49.

To calculate the probabilities, we need to consider the number of white and black fuses in each toolbox.

First, let's determine the total number of fuses in each toolbox:

First Toolbox:

Total fuses = 4 white fuses + 3 black fuses = 7 fuses

Second Toolbox:

Total fuses = 3 white fuses + 5 black fuses = 8 fuses

(a) The probability that the fuse drawn from the second toolbox is black:

The probability of drawing a black fuse from the second toolbox depends on the fuse selected from the first toolbox. There are two scenarios to consider:

Scenario 1: The fuse selected from the first toolbox is black.

In this case, the second toolbox will have 3 black fuses remaining out of the total 7 fuses.

Probability = (Number of black fuses in the second toolbox)/(Total number of fuses in the second toolbox)

Probability = 3/7

Scenario 2: The fuse selected from the first toolbox is white.

In this case, the second toolbox will have 5 black fuses out of the total 7 fuses.

Probability = (Number of black fuses in the second toolbox)/(Total number of fuses in the second toolbox)

Probability = 5/7

To calculate the overall probability, we need to consider the probability of each scenario and weigh it by the probability of selecting a fuse of that color from the first toolbox. Since the fuse from the first toolbox has an equal chance of being white or black, we need to take an average of the probabilities in both scenarios.

Probability of drawing a black fuse from the second toolbox = (Probability of scenario 1 + Probability of scenario 2)/2

Probability of drawing a black fuse from the second toolbox = (3/7 + 5/7)/2

Probability of drawing a black fuse from the second toolbox = 8/14

Probability of drawing a black fuse from the second toolbox = 4/7

Therefore, the probability of drawing a black fuse from the second toolbox is 4/7.

(b) The probability that the fuse drawn from the second toolbox is white:

Similarly, we can calculate the probability of drawing a white fuse from the second toolbox. It will be the complement of the probability of drawing a black fuse.

Probability of drawing a white fuse from the second toolbox = 1 - Probability of drawing a black fuse from the second toolbox

Probability of drawing a white fuse from the second toolbox = 1 - 4/7

Probability of drawing a white fuse from the second toolbox = 3/7

Therefore, the probability of drawing a white fuse from the second toolbox is 3/7.

(c) The probability that one is white:

To calculate the probability that one fuse is white, we need to consider both scenarios: either the fuse drawn from the first toolbox is white and the fuse drawn from the second toolbox is black, or the fuse drawn from the first toolbox is black and the fuse drawn from the second toolbox is white.

Scenario 1: Fuse drawn from the first toolbox is white, and the second toolbox has a black fuse:

Probability = (Probability of drawing a white fuse from the first toolbox) * (Probability of drawing a black fuse from the second toolbox)

Probability = (3/7) * (5/7)

Scenario 2: Fuse drawn from the first toolbox is black, and the second toolbox has a white fuse:

Probability = (Probability of drawing a black fuse from the first toolbox) * (Probability of drawing a white fuse from the second toolbox)

Probability = (4/7) * (3/7)

To calculate the overall probability, we need to sum up the probabilities of both scenarios:

Probability that one fuse is white = Probability

of scenario 1 + Probability of scenario 2

Probability that one fuse is white = (3/7) * (5/7) + (4/7) * (3/7)

Probability that one fuse is white = 15/49 + 12/49

Probability that one fuse is white = 27/49

Therefore, the probability that one fuse is white is 27/49.

If it is subjected to the couple determine the maximum shear stress in regions AC and CB of the shaft. G st = 75 GPa. Than the answer will be 52Mpa.

We need to perform a two step process to obtain the maximum shear stress on the shaft. For the solid shaft,

P=2×pi×N×T/60 or T=60×p/2×pi×N

Where P=power transmitted by the shaft=50×10³W

N=rotation speed of the shaft in rpm=730rpm

Pi=3.142

T is the twisting moment

By substituting the values for pi, N and P, we get

T=654Nm or 654×10³Nmm

Also, T=pi×rho×d³/16 or rho=16×T/pi×d³

Where rho=maximum shear stress

T = twisting moment=654×10³Nmm

d= diameter of shaft= 40mm

By substituting T, pi and d

Rho=52Mpa

b. For a hollow shaft, the value for rho is unknown

T=pi×rho(do⁴-di⁴/do)/16

Rho=T×16×do/pi×(do⁴-di⁴)

Where

T= twisting moment=654×10³Nmm gotten above

do=outside shaft diawter=40mm

di= inside shaft diameter =30mm

Pi=3.142

Substituting values for pi, do, di and T.

The values of the finite numbers A and to such that the Laplace transform G(s) of g(t) = Ae-51 u(-t-to) has the same algebraic form as X(s) will be - 1 and the region of convergence corresponding to G(s) is 1.

Therefore based on the information, the region of convergence corresponding to G(s) will be To = -1 and A = 1.

Answer:

The above three conditions are commonly referred to as the equations of equilibrium for planar structures. ∑ Fx and ∑ Fy are the summation of the x and y components of all the forces acting on the structure, and ∑ Mz is the summation of the couple moments and the moments of all the forces about an axis z, perpendicular to the plane xy of the action of the forces.
